Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for attaching a trim of an automobile, and more particularly to a structure for attaching a seaming welt and a side trim to a flange at an opening edge of a vehicle body.

(Prior Art) In automobiles, a trim is provided to cover the interior walls of the vehicle for decoration, etc., and a seaming welt is attached to the flange at the edge of the opening in the vehicle body.
Preferably, the trim is attached so that there is no gap between the trim and the seaming welt. For this reason, a method has been adopted in which the trim is attached without creating a gap between the trim and the seaming welt by providing a locking part on the trim that is held by the seaming welt together with a flange at the edge of the opening of the vehicle body.

Furthermore, the trim is provided with a rib that comes into contact with the vehicle body wall in the opposite direction to the direction in which the flange extends, that is, in the direction in which the seaming welt is inserted, so that the rib comes into contact with the vehicle body wall when the seaming welt is inserted. to prevent the trim from shifting,
Trim attachment directions have also been developed to ensure that the trim is retained in the seaming welt.

(Problem to be Solved by the Invention) However, in the mounting direction of these trims, a method is adopted in which a core material is firmly fixed to a panel of the vehicle body with screws, and the trim is attached to this core material. However, for such screw fixing, it is necessary to provide a hole penetrating to the outside at the bottom of the vehicle body, below the door attachment portion. It is undesirable to have a through hole in the vehicle body because it allows moisture such as rainwater and noise from outside to enter.
Therefore, there is a need for a trim mounting structure that reliably attaches the trim without using parts such as screws or fasteners, without creating holes in the vehicle body, and without causing misalignment between the seaming welt and the trim. There is.

In view of the above-mentioned problems, the present invention has been developed to attach mutually different members, a seaming welt and a trim, to the flange part of the opening edge of the car body, without causing any misalignment between the two, and without using parts such as screws or fasteners. It is an object of the present invention to provide an automobile trim mounting structure that can be securely mounted without making holes.

(Means for Solving the Problems) In order to solve the above problems, the automotive trim mounting structure according to the present invention has one end of the first U-shaped part having a U-shaped cross section that fits into the flange of the opening edge of the vehicle body. A U formed by extending on the indoor side and forming a second U-shaped part having a U-shaped cross section in the opposite direction to the first U-shaped part.
A seaming welt is fitted to the first U-shaped portion of the clip from the outside, and a part of the seaming welt and a portion that abuts the seaming welt are fitted to the second U-shaped portion. The seaming welt is characterized in that a protrusion formed on the inside of a trim separate from the seaming welt is inserted and held in place.

The above-mentioned U-shaped joint type elastic clip is an elastic clip that extends one end of a metal clip with a U-shaped elastic cross section.
A second U-shaped part is formed in the opposite direction to the first U-shaped part by sharing a part with this first U-shaped part, and is configured in a type in which two U-shaped elastic clips are connected. It is something that

(Function) The above-mentioned U-shaped joint type elastic clip is attached to the vehicle body by fitting the first U-shaped portion into the flange of the opening edge of the vehicle body using elasticity, with the second U-shaped portion facing the interior side. Furthermore, from the outside of this first U-shaped part,
A seaming welt having a U-shaped cross section and which the trim is in contact with is fitted. This seaming welt is fitted into the first U-shaped portion from the outside, and at the same time, a portion of the seaming welt is fitted into the second U-shaped portion. A part of the indoor side of this seaming welt is contacted with a trim from the outside, and the inside of this trim has a
A protrusion is formed to fit into and lock into the second U-shaped portion, and this protrusion is press-fitted into the second U-shaped portion together with a portion of the seaming welt. Therefore, the trim abuts against the seaming welt without leaving a gap, and the press-fitting also ensures that the seaming welt is fitted into the U-shaped elastic clip.

That is, the U-shaped elastic clip reliably locks the vehicle body and the seaming welt, and the seaming welt and the trim, making it possible to attach the trim to the vehicle body without creating a gap between the trim and the seaming welt.

Therefore, the trim can be securely installed without using parts such as screws, fasteners, or mounting holes.

This U-shaped joint type elastic clip does not need to be provided along the entire length of the seaming welt, but by providing it at several locations where necessary, the trim can be fixed to the seaming welt without causing any displacement.
